"An Alberta beef cow just under seven years of age. No part of theanimal has entered the human food or animal feed systems."

The cow has just been hanging around for seven years? How long does it take a beef cow to reach full size for slaughter? I wouldn't think seven years. If it were a dairy cow the seven years might be more understandable. If it were a dairy cow, then it is true that no "part" of the animal entered the human food supply. Milk isn't really a "part" of the cow. Is my line of thinking off base?
